Factors of 144

Definition of a Factor

A factor of a number is another number that divides it without leaving a remainder. In simple terms, a factor is a whole number that can be multiplied by another whole number to get the original number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. These numbers can divide 12 without leaving a remainder and can be multiplied together to equal 12.
